The Contractor is required to provide the Control System for each of the turnout buildings as described in Section 25 00 01 1.05 A as well as the interface to the remote San Juan Lateral SCADA System, including the optical fiber transmission lines, as described in Section 25 00 01 1.05 C and as shown on the Network Overview Drawing, 1695-D-62588.

• A future amendment removes the installation of the Government Furnished Network Integration Panels from the contractor's scope (refer to Section 25 00 01 paragraph 1.05 C), and changes the timeframe for onsite support requiring coordination with the Lateral SCADA Installer Contractor and the COR (refer to Section 01 80 15 paragraph 3.01 J). Network Overview Drawing 1695-D-62588 also provides information on the Contractor's optical fiber installation. Note 4 on that drawing will be changing with the upcoming amendment. Additionally, Section 25 08 10 - Automation System Testing and Acceptance will be removed in from the package and Section 01 80 15 - Commissioning will be added.

• There are no motors included in this project.

14 9/9/2026

Resolve TP10 laboratory conflicts, TP2 missing text, swapped water/date entries, and provide final bearing, settlement, swell, shear, thermal and groundwater recommendations. (G1–G25)

• It is noted that the visual classification is not the same as the laboratory classification on the test pit log for test pit TPTB-25-10. These classifications are not always the same since a visual classification is not an exact science. Also, the test pits at the turnout buildings were conducted within the previously disturbed construction right away. This resulted in mixed backfill that is not stratified the way normal soil is deposited. There can be a lot of variation in soil type within the same test pit, depending on where the sample/density is collected.

• A corrected TP2 test pit log will be included in a future amendment.

• It is noted that the Depth to Water and Date entries are swapped, however, corrected test pit logs will not be issued.

• Any geotechnical data beyond what is currently provided is the responsibility of the contractor. Additionally, geotechnical recommendations, including field investigations and laboratory testing required to support Contractor recommendations, are the responsibility of the Contractor. Refer to Specification Section 13 34 00 Prefabricated Engineered Structures, Part 1.05 B, which states that "The Contractor is responsible for the Foundation Design of the Turnout Buildings" which includes field investigations (Part 1.05 B.1) and geotechnical laboratory testing (Part 1.05 B.2).

Specification section 09 96 20 gives multiple options for the coatings and linings that are acceptable, additionally, the contractor can propose equal alternatives to those listed in the tabulations. Specification section 26 42 00 states the performance criteria required to be met by the cathodic protection system however, 26 42 00 and 26 42 11 are prescriptive specifications for the cathodic protection system. These specifications do not request the contractor to design a cathodic protection system. Therefore the soil data is not provided but the system was designed to meet the performance criteria.

18 9/9/2026 Confirm the 6-in gravel/geotextile limits within each compound, including treatment beneath buildings, pads, stoops, swales and riprap. (Site plans)

The informational drawings (P75 - P114 of the drawings PDF) do not add demolition or construction scope. They are included for informational purposes only.

20 9/9/2026

Identify environmental permits, flow restrictions, access windows, cultural-resource controls, and restoration requirements for the BBN9 low-water crossing. (Schedule 4 CLIN 4-17 / P29–P30 / prebid slides)

• Environmental permits: The wash is classified by the National Wetlands Inventory as R4SBJ, which is an intermittent stream. Intermittent streams are no longer considered to be jurisdictional under the Clean Water Act, and therefore a Section 404 permit is not required. A SWPPP will be required as detailed in section 01 57 30.

• Flow restrictions/Access Windows: The BBN9 low water crossing (drawings 1695-D-62546 and 1695-D-62547) is constructed in a wash that is dry except after precipitation events.

For each dataset, identify the NAD83 realization/epoch, horizontal and vertical units, NAVD88/geoid basis, grid-versus-ground treatment, factor/origin, control points, localization/transformation, survey date, and revision/provenance. Clarify masked, obscured, disconnected, or text-only contour/elevation data and confirm whether the supplied data are authorized for bid earthwork quantities; if native data will not be issued, provide the Government-directed measurement basis and assumptions.

*For Sanostee, provide the Four Corners survey referenced by 1695- D-62529 Note 6, confirm the vertical datum and excavation-center basis of G6/G13/G14 test-pit elevations 5564.7/5564.8, and confirm whether preliminary combined-PDF page 113 and the 2019 page-88 profile are authorized/current.

*For Window Rock, reconcile the Reach 12.2 factor

It is the responsibility of the contractor to coordinate with the COR to verify cPWS entry points. Refer to section 35 21 95 - Steel Manifold Piping paragraph 3.01. Drawing PDF page 88, drawing 1695-D-6068 is the final design P&P drawing showing the location of the sanostee turnout on Reach 4C. An as-built drawing is not yet available. It is the responsibility of the contractor to confirm the locations of the existing lateral turnout tie-ins prior to fabrication of steel manifold piping. Refer to section 35 21 95 - Steel Manifold Piping paragraph 3.01

• The Reach 12.2 grid to ground scale factor of 1.00027992033 is correct for the Window Rock Site. Drawing 1695-D-62544, detailing the window rock access road, will be revised to show the correct grid to ground scale factor. The revised drawing will be included in a future amendment.
